WebGL

The EXT_texture_filter_anisotropic WebGL extension has been unprefixed. Using "MOZ_EXT_texture_filter_anisotropic" will present a warning from now on. The prefixed name is going to be removed in a future release (bug 776001).

SVG

No change.

MathML

The parsing of the align attribute on <mtable> elements has been updated to treat optional spaces more correctly.

User Agent

The Gecko part of the user agent string changed. The build date (which hadn't been updated since 2010) was removed, and the Gecko version number was put in its place instead. So Gecko/20100101 -> Gecko/17.0. This may affect you if you are doing user agent sniffing.
